ComboBox in a Grid displayed as RowLevelDetails works with Keyboard but not Mouse

I have a Grid which is used to display a heirarchical Domain Objects. When I click no the parent row, the RowDetailsTemplate

is defined as a grid as well.

For Example assume my observableCollection heirarchy is Customer which has a Collection of Orders. When I click on a customer in the grid, my RowDetailsTemplate shows me a "nested" grid of Orders.

This solution is from Colin E. and it works great especially for displaying readonly information.

The child grid (the Orders) can even be edited as well! What I am now seeing is the need for a combobox for one of the column in the nested Grid.

I was able to get the ComboBox to show but it has very strange behavior: I can select from the combobox only when I use the keyboard. When I use the mouse, it appears to ignore the selection make an resets to the loaded (bound) value.

It appears that the parent row receives the same SelectionChanged event as the child combobox. Using the JanRelease, there is a workaround that includes canceling the ParentEvent and allowing the ChildEvent to continue. (Thanks Mahender for finding that
solution!)

It appears that this is addressed as a bug fix in the March2009 release, however. Does anyone know which bug is related to this issue (which work item?)

Also, is there a full list of release note for the March09 wpftoolkit? I used the advanced search on issue tracker an didn't see any associated with the March Release.
